Until now double clicking in Qt 5 resulted in the following sequence of mouse
events: pressed, released, double clicked, released. This is wrong, the press
belonging to the second button down is missing. In Qt 4 that pressed event is
present.
The problem is not apparent in desktop environments because the double click is
functioning properly even when the second pressed is missing. However when
using a platform plug-in like wayland, where the clients receive only press,
move and release events, double click was broken because the second click was
effectively ignored (due to receiving nothing but a button release).
